T0 a/ZZ whom it Wray cm1/cern:

Be it known that I, ANTON F. FLIERooM,'a citizen of the United States.residing at Elizabeth, in the county of Union and State otNew Jersey,`have invented certain new andusei'ul Improvements in Trolley Devices,of which the following is a specification, such as will enable thoseskilled in the art to which it appertai'ns to make and use the same.

This invention relates to trolleyY devices for trolley-cars; and theobject thereof is to provide an improved device of this class which isconstructed in such manner as to hold the trolley wire or conductor inconnection with the trolley wheel at all times and prevent thetrolley-wheel from being accidentally detached from the wire orconductor in the operation of the trolley or of a ear provided with atrolley.

The invention is fully disclosed in the following specilication, ofwhichQthe accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach ofl the views, and in which- Figure 1 is a side view of my improvedtrolley device, and Fig. 2 asection on the line 2 2 of Fig. 1.

In the practice of my invention I provide a fork a oi the usual or anydesired formand with which the trolley-arm b may be connected in theusual or any desired manner. The sides of the fork t are provided attheir ends with thickened heads a2, and passed there-.

through is the shaft or aXle c, on which the trolley-wheel lis mounted,and passing through each end of the shaft or axle c is a pin c2, and theouter sides of the heads a2 of the fork a are provided with transverserecesses c3, through which said pins are also passed, and thisconstruction prevents the shaft or axle c from turning in the fork cr.

At each side of the wheel dis-placed a supplemental wheel or disk e, andthese wheels or disks are each provided at the perimeter thereof with aplurality of radially-projecting lingers or members e2, which in form ofthe construction shown are six in number on each Wheel or dlsk, and eachof said fingers or members is provided with an inwardly-directedprojection or dog e3, the outer surfacesof which are curved` inwardlytoward the center of the wheel CZ, as shown in Fig. 2, and the innersurfaces of which are curved outwardly and inwardly.

Between each of the wheels or disks e and the side arm of the fork t isplaced an independent and rotatable hub f, and in the form ofconstruction shown these hubs are provided with journal members f2,which pass through the wheels or disks e and on which said wheels ordisks e are free to turn, and within the' hubs j are placed spiralsprings g, and said hubs are preferably provided with spiral grooves inwhich said springs fit, and these springs g are so placed that the endsthereotl bear on the wheel d and on. the side arms of the fork a, andthe object of these springs is to provide means for preventing thebreaking of the circuit caused byl the jumping, jolting, or jarring ot'the trolley device in the operation of the car and afterk the parts ofthe trolley device become worn. The wheel 0l is also provided with theusual oiling ports or passages /t and-the wheels or disks e withcorresponding ports or passages 7b2, through which the wheel Z and theshaftv or axle c may be oiled or lubricated whenever desired; butmyinvention is not limited to any particular form of oiling orlubricating means 0r devices, and any suitable construction by whichthis result can be accomplished may be employed. l

In Fig. 2 Ihave indicated at 7,' a trolley wire or conductor, and thespace between the inwardly-directed dogs or projections e3 is suiicientto allow the said wire or conductor to be passed into the groove 2 ofthe wheel d in the usual manner, and in the operation of this device thewheels or disks@ are free V.to 9c turn with or independently of thetrolleywheel d, and the dogs or inwardly-directed projections e3 serveto hold the wire or conductor e' in proper position with reference tothe wheel al at all times, and the shape of the said inwardly-directeddogs or projections is such that the wire or conductor a' will not underany ordinary circumstances jump out of the groove 2 in the operation ofthe trolley device and said trolley device will not become accidentallydisconnected from said wire or conductor. It will be observed that vltheradially-arranged fingers @2 of the wheels or disks e and theinwardly-directed projections or disks e3 are so arranged that two ofthem on each side are always in operative position or extend over thewire or conductor z' when the latter is in the groove of thetrolleywheel, and it is also a well-known fact that the disconnection ofthe trolley wire or conductor and the trolley device is usuallyoccasioned by a vertical and lateral movement of the trolley device,especially at curves or crossings, and the inwardly-directed projectionsor dogs e3, arranged as above described, will serve to prevent at alltimes any lateral disconnection of the wire and the trolley device orany disconnection which might be occasioned by jumping, jolting, orjarring and by lateral movement of the trolley device, and in order todisconnect the wire or conductor z' the parts must be in proper positionand the movement of the trolley device must be exactly so that the wireor conductor will pass between the projections or dogs a3, and this isalso true in connecting the wire or conductor with the trolley devicewhen said parts have been disconnected.

It will be understood that in passing a crossing the transverse wires orconductors or any transverse support of any kind for the wire orconductorfl the radially-directed lingers or projections e2 and theinwardly-directed projections or dogs e3, connected therewith, strikethe cross-Wire or the transverse support of the wire or conductor t' andthe wheels or disks e are free to turn, and the trolley device is thusenabled to pass freely under any such obstruction without danger ofbreaking or any serious interference.

M y improved trolley device is simple in construction and operation andperfectly adapted to accomplish the result for which it is intended, andvarious changes in and modifications ofthe construction herein shown anddescribed may be made withoutdeparting from the spirit of my inventionorsacriiicing its advantages.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A trolley device, comprising a block, a shaft or axle mountedtherein, a trolley-wheel mounted on said shaft or axle, and independentand rotatable wheels or disks mounted on the opposite sides of thetrolley-wheel, said wheels or disks being provided at their perimeterswith radially-projecting lingers having inwardly-directed dogs the innersurfaces of which are inclined donuiwardly and inwardly and the outersurfaces of which are also inclined downwardly and inwardly,substantially as shown and described.

2. A trolley device, comprising` a block, a shaft or axle mountedtherein, a trolley-wheel mounted on said shaft or axle, and independentand rotatable wheels or disks mounted on the opposite sides of thetrolley-wheel, said wheels or disks being provided at their perimeterswith radially-projectingiingers having inwardly-directed dogs the innersurfaces of which are inclined downwardly and inwardly and the outersurfaces of which are also inclined downwardly and inwardly, and saidshaft or axle being also provided at the opposite sides of thetrolley-wheel and on the outer sides of the independent wheels or diskswith independent hubs in which are placed spiral springs, substantiallyas shown and described.

In testimony that 1 claim the foregoing as my invention I. have signedmy name, in presence of the subscribing witnesses, this 27th day ofJanuary, 1905.
